Question 341Navigation General

The correct answer is A) yellow. Buoys that mark dredging areas are painted yellow in accordance with the U.S. Aids to Navigation System. This is to help mariners easily identify and avoid these active dredging areas, which can pose navigational hazards. The other answer choices are incorrect because red, green, and black buoys have different meanings and uses within the navigation system, but are not the standard color for marking dredging areas.
